If intending to use a cylinder by a different
manufacturer it is advisable to confirm
beforehand that the new cylinder will fit the boss.
Note that the CL5000 uses a 6 pin screw-cap
cylinder. The CL4000 use a 5 pin cylinder.
THESE TAILPIECES WILL FIT MOST SCREW-CAP CYLINDERS FROM
OTHER MANUFACTURERS
CAUTION! DO NOT INSERT THE KEY IN THE CYLINDER ONCE YOU HAVE REMOVED THE SCREW-CAP
5. Test the key operation. If the key is difficult
to insert or tight when turning, then the cap
maybe too tight. Loosen the cap one notch
at a time and try the key again. If the key
inserts and turns OK, but is difficult to
remove, then the cap may be too loose.
Tighten up the cap one notch at a time.
Adjust the cap until the key inserts, turns
and removes easily.
